Nonfunctioning, small, incidental pancreatic neuroendocrine tumors: Results of a nonoperative approach cohort.

Objective: The availability of new imaging techniques has conditioned an increase in the incidental diagnosis of small nonfunctioning pancreatic neuroendocrine tumors (PNET-NF). The best treatment is controversial, some authors advise a conservative approach in selected cases. Our aim is to analyze the evolution of incidental, small size PNET-NF, treated with clinical follow-up without surgery.

[Minimising hospital costs in the treatment of bile duct calculi: a comparison study].

Introduction: The treatment of bile duct calculi associated with cholelithiasis is controversial. The hospital costs could be a decisive factor in choosing between the different therapeutic options.

Objectives: To compare the effectiveness and costs of two options in the treatment of common bile duct calculi: 1) One-stage: Laparoscopic cholecystectomy and bile duct exploration, and 2) Two-stage: sequential endoscopic retrograde cholangiopancreatography and laparoscopic cholecystectomy.
